Due to technological limitations for the development of onion hybrids, first-cycle synthetic varieties (Syn1-SV) could be an alternative to partially explore heterotic vigor. The growing areas of onion hybrids in Brazilare mainly defined by bulb yield and uniformity. From this perspective, the present study aimed to developtropical onion Syn1-SV and estimate mid-parent heterosis (Hm), heterobeltiosis (Hp), and standard heterosis(Hs) as an alternative to hybrid development. Six Syn1-SVs, eight open-pollinated (OP) populations, and onecommercial hybrid were evaluated in a randomized block design with three replications, in two semesters, forthe commercial bulb yield (CBY) and days to bulb harvest (DBH). Significant differences were observed fortreatments (T), semesters (S) and the T*S interaction for both variables (p-value<0.05). The OPs ‘Alfa SF RT’ inthe first semester and ‘IPA11’ in the second semester were the most precocious treatments. The highest CBYwas estimated in the commercial hybrid (105.8 t ha-1) and in ‘Alfa SF RT’ (45.5 t ha-1) in the first and secondsemesters, respectively. Three Syn1-SVs showed positive Hm values, ranging from 2.0% to 6.3% for CBY. ThreeSyn1-SV showed positive Hp values in the first semester, ranging from 3.0% to 5.2%, for CBY. Only the Syn1-SV ‘AlfaSF RT’ × ‘BRS Alfa São Francisco’ (48.9 t ha-1) showed positive Hs values, surpassing by a small value the controlOP population ‘IPA11’ (48.0 t ha-1), indicating the potential of Syn1-SV as an option for onion hybrids.

Plant growth-promoting bacteria (PGPB) from drylands are promising biological resources to mitigate thenegative effects induced by water deficit. The aim of this study was to evaluate the effects of bacteria nativefrom the Caatinga biome on the initial growth of melon plants subjected to water deficit. Nine bacteria (M1.1,T11.2, PH5.2, T11.1, T2.1, T1.1, M7.1, XX6.9 and XX6.6) isolated from Caatinga soils were tested in two varietiesof melons (Cantaloupe and Yellow) cultivated under two water availability scenarios (50% irrigation and 100%irrigation of the crop evapotranspiration - ETc). In the control treatment, no inoculation was performed. Theeffects of the treatments on shoot length (SL), shoot dry mass (SDM), root length (RL) and root dry mass (RDM)were evaluated. In the scenario without water deficit (100% ETc replacement), the isolates PH5.2, T2.2, M7.1,XX6.9 promoted (p<0.05) the root and shoot biomasses in the Cantaloupe variety, while in the Yellow variety,growth promotion was sporadic, with three isolates (M1.1, M7.1 and XX6.9) promoting at least one parameterevaluated. In the scenario with a water deficit (50% ETc replacement), isolates T1.1 and XX6.9 promoted thetotal biomasses (SDM and RDM) of the Cantaloupe and Yellow varieties, respectively. All isolates stimulated RL inthe Cantaloupe variety. Bacteria isolated from the Caatinga promote growth and reduce the effects of waterdeficit in melon and thus are potential inoculants to enhance production in the early stages of melon cultivationin semiarid regions.

Under salt stress, plant growth and development are negatively affected due to physiological changes,requiring strategies such as fertilization management to minimize these effects. In this scenario, this study aimedto evaluate the effect of combinations of nitrogen, phosphorus, and potassium on the growth, leaf waterstatus, electrolyte leakage, and gas exchange of West Indian Cherry grown under water stress in the secondyear of production. The experiment was conducted in a protected environment in Campina Grande - PB.The treatments were distributed in a randomized block design with a 2 × 10 factorial arrangement with threereplications corresponding to two electrical conductivity levels of irrigation water– ECw (0.6 and 4.0 dS m-1)and ten combinations of fertilization with nitrogen, phosphorus, and potassium (80-100-100; 100-100-100; 120-100-100; 140-100-100; 100-80-100; 100-120-100; 100-140-100; 100-100-80; 100-100-120, and 100-100-140% of therecommendation in the second year of production). Irrigation with the ECw of 4.0 dS m-1 negatively affectedplant growth, the leaf water status, electrolyte leakage, and the leaf gas exchange of West Indian Cherry.However, the 40% increase (C4 -140-100-100% of the recommended N-P2O5-K2O level) in the nitrogen levelmitigated the deleterious effects of salt stress on the relative water content, internal CO2 concentration, and theCO2 assimilation rate of West Indian Cherry plants in the second year of production.

Potato (Solanum tuberosum, L.) is one of the most responsive crops to fertilizer application, which drives theneed to rationalize and make the most of nutritional resources in efficient and sustainable management. Basedon the hypothesis that the organomineral is a great alternative to increase potato productivity (Ágata andAtlantic cultivars) and that it can be indicated as a substitute for mineral fertilizers, this study aims to evaluatethe effect of organomineral doses applied in the planting furrow on potato productivity to identify the bestlevel of mineral fertilizer replacement. A study was conducted in the city of Cristalina (state of Goiás, Brazil),evaluating the replacement of 40, 60, 80, and 100% of mineral fertilizer (standard) provided via organomineralfertilizer in two widely cultivated varieties. The total productivity and the productivity in classes were monitored,as well as the nutrient contents in the leaves. The results showed that the organomineral is a great alternative toincrease potato productivity and can be indicated as a substitute for mineral fertilizers. For the cultivar Ágata,an organomineral dose of 80% is recommended concerning mineral fertilization. On the other hand, for theAtlantic cultivar, the same dose of mineral fertilizer is recommended. In both cultivars, there was an increase intuber size with organomineral fertilization, which indicates greater efficiency in tuber productivity.

Pineapple is the third most cultivated tropical fruit in the world. However, few studies have focused on the cultivationusing organic fertilization, especially in semiarid regions. Thus, this study aimed to evaluate growth, production andphysicochemical traits of pineapple fruits produced under organic fertilization in the semiarid. The experiment wascarried out at the didactic orchard of Federal Rural University of Semiarid, Mossoró, Rio Grande do Norte, Brazil. Fourfertilization treatments were studied (chemical fertilizer, cattle manure, goat manure, poultry litter). At 18 monthsafter planting, plant growth, physicochemical traits of fruits, and productivity were evaluated. Results showed thatorganic fertilization with poultry litter provides best results for physicochemical traits of fruits and productivity of ‘Pérola’pineapple. Organic fertilization with poultry litter is most promising for plant growth, physicochemical traits of fruits, andproductivity in ‘Pérola’ pineapple, therefore, the most suitable for cultivation in the semiarid region. The fruit firmness,central cylinder weight, and ratio SS/TA showed best values under chemical and goat manure fertilization.

The aim of this study was to evaluate the physicochemical and functional characteristics of fruits yielded bypeach trees which were fertilized with different doses of nitrogen. The experiment, which was installed in 2014.It had a randomized complete block design with four replicates. The nitrogen rates applied were 0, 40, 80,120, and 160 kg N per hectare. Fruits were harvested in four crops in a row (2014, 2015, 2016, and 2017). Theparameters were evaluated: soluble solids, pH, titratable acidity, epidermis and pulp firmness, attributes of pulpcolor, carotenoids, phenolic compounds, and antioxidant activity. Responses were only related to luminosity inthe first crop. However, N fertilization influenced not only the soluble solid content, pH and chroma in the secondcrop but also all attributes of color in the third crop. SS, pH, ºHue and chroma differed among treatments inthe fourth crop. The more N in the first three crops, the more carotenoids. Phenolic compounds decreasedsignificantly in the 2016 crop whereas antioxidant activity diminished in both the 2015 and 2016 crops. Eventhough an ideal dose of N cannot be recommended due to high variation in attributes in the years underevaluation, it is needed because of other factors, such as weat her.

Hydroponic solution from agricultural organic waste can be used as an alternative to chemical solutions and strongly increases the growth and yield of Chinese cabbage plants. This study was to obtain formulations, concentrations, and their interactions that have the potential to increase the agronomic, physiological, biochemical, and yielding characteristics of Chinese cabbage in hydroponic culture. This study was conducted from September to November 2022 using a randomized block design with two factors and three replications. The first factor was the formulation of organic nutrient solutions (F1= banana peels+bean sprouts+eggshells; F2= banana humps+onion peels+bean sprouts+moringa leaves; F3= moringa leaves+onion peels+bean sprouts; F4=AB mix as a comparison). The second factor was the concentrations (600; 900; 1,200; 1,500 ppm). Data were analyzed using ANOVA and proceeded with the Duncan at P<0.05. The results showed that formulations F3 and F2 significantly increased Mg and chlorophyll b levels while formulation F1 increased nitrate and flavonoids. The concentrations ranged from 1,200 to 1,500 ppm showed the highest yield and shoot fresh weight were 2.86 kg m-2 year-1 and 30.70 g. The F3C4 interaction was highly recommended to increase the yield of Chinese cabbage by 2.68 kg m-2 year-1 compared to the other liquid organic fertilizers and it could be used as a substitute for using liquid chemical fertilizers in hydroponic culture.

Studies on species of the family Myrtaceae are mostly related to floristic surveys, reproduction involving large plant communities, and family taxonomy. Thus, the objective of this study was to elucidate aspects of the floral and reproductive biology, as well as floral visitors of ubajai (Eugenia myrcianthes Nied.). Studies were conducted on floral morphology and morphometry, identification of nectaries and structures attractive to floral visitors, characterization of floral visitors, stigma receptivity, and androecium maturation, pollen storage, in vitro viability testing, and characterization of the reproductive system. Ubajai flowers open at approximately 6:00 a.m., and their anthers are the main attractive structure to floral visitors. The main floral visitors and effective pollinators of ubajai are honeybees (Apis mellifera). The addition of 40% sucrose to the culture medium, using fresh pre-anthesis pollen, allows for a 90% germination rate. Ubajai pollen is recalcitrant, thus, it loses viability before 30 days of storage, even when stored in a refrigerator, freezer, liquid nitrogen, or natural environment. Ubajai can be considered a self-compatible plant; however, fertilization of flowers through cross-pollination also occurs, and apomixis does not occur.

Thus, the objective of this study was to elucidate aspects of the floral and reproductive biology, as well as floral visitors of ubajai (Eugenia myrcianthes Nied.). Studies were conducted on floral morphology and morphometry, identification of nectaries and structures attractive to floral visitors, characterization of floral visitors, stigma receptivity, and androecium maturation, pollen storage, in vitro viability testing, and characterization of the reproductive system. Ubajai flowers open at approximately 6:00 a.m., and their anthers are the main attractive structure to floral visitors. The main floral visitors and effective pollinators of ubajai are honeybees (Apis mellifera).

This experiment was designed, it was determined the effects of mycorrhiza, vermicompost, promalin applications on development of plant properties in a bulbous plant, Lilyum 'Adelante. Flower branch length (cm), flower branch diameter (mm), internode number, flower bud number, flower bud length (cm), flower stem length (cm), flower width (cm), flower length (cm), number of leaves and leaf length (cm) were measured. The results showed that no treatment increased plant height more than control plants, but each application had different effects on other plant characteristics. As a matter of fact, mycorrhiza increased internode number, flower bud number, flower bud length, flower stem length, flower length, number of leaves and leaf length by 6.3%, 15.6%, 14.2%, 6%, 40%, 10.3%, 2.9% and 6%, respectively. Vermicompost increased flower bud length, flower length and leaf length by 6.6, 12, 15.3% and 16.1%, respectively. Promalin, on the other hand, increased the flower stem length, flower length and leaf length by 56.3% and 15.4%, respectively. The application of mycorrhiza together with Promalin did not have a different effect than the application of Promalin alone, and even showed a lower effect than the application of Promalin alone. Mycorrhiza, on the other hand, was the application that showed the best effect compared to other applications. Therefore, it can be recommended for plant growth in lilies. However, due to the effect of application time and dose on flowering time, it is possible to obtain different results in plant development in lilies.

A rosa do deserto tem ganhado notoriedade no mercado ornamental de flores por ser plantas belíssimas e de fácil manejo, entretanto, ainda são poucas as informações sobre o cultivo da espécie. Tendo em vista essa problemática, objetivou-se avaliar substratos formulados a base de bagana de carnaúba (Copernicia prunifera Mill.), casca de arroz carbonizada (Oryza sativa L.), caule decomposto de babaçu (Attalea speciosa) e solo, com diferentes profundidades de semeadura, tipos de sombreamento e lâminas de irrigaçãoara produção de mudas de Adenium obesum . Foram adotados delineamento inteiramente casualizado em esquema fatorial 4x3. Como variáveis avaliadas: germinação, índice de velocidade de emergência, altura da planta, altura do caudex, número de folhas, diâmetro do caule, diâmetro do caudex, comprimento radicular, massa seca e fresca das partes aéreas e raiz, volume da raiz e índice de qualidade de Dickson. Mediante os resultados as mudas se desenvolveram melhor sob profundidade de semeadura de 10 mm e substrato com 100% a.C. Como telas de sombreamento não influenciam no desenvolvimento, recomendando o uso do ambiente a céu aberto. E ainda utilizando o mesmo substrato é indicado lâminas entre 50 e 75% da capacidade de vaso, já para os substratos demais, recomenda-se a lâmina de 25%.
